Investigation of Coatings Containing Tremolite Non-Asbestiform to Determine if Abrasive Blast Fragments Contain Asbestos
Do coatings that contain tremolite non-asbestiform during removal process break down into fragments considered asbestos?
Need and Benefit
The regional offices are interested in this study to determine if tremolite and anthophyllite break down into asbestos during surface preparation activities. There are a few coating materials in our coating guide specifications that contain tremolite and anthophyllite, non-asbestiform. These coatings outperform the other coatings on the market, and Reclamation has been using these products for the past 25 years. Just like lead and chromate primers, these materials may be a safety and health issue, and we just do not know about it at this time.
A few industrial hygienists have brought this to my attention and would like to further investigate if the byproducts from coating removal process will contain asbestos fragments. This would truly be a safety issue if these byproducts contain asbestos because it is used on almost every project across Reclamation.
